Omacosy brings Hyprland-style tiling window manager to macOS without SIP disablement

Omacosy packages a tiling window manager, status bar, and workspace overview into a single repository that installs without disabling System Integrity Protection. The project replaces what would typically require multiple third-party dependencies with five signed Swift binaries, reducing the attack surface and avoiding compatibility issues with macOS 26. Memory footprint remains low, approximately 157 MB on a single display, by sharing system frameworks across processes and caching only visible window thumbnails in the overview daemon.

The installation process is idempotent and scripted, cloning the repository to a specific location to avoid macOS privacy restrictions on certain directories. Updates are manual but streamlined: a single command pulls changes and recompiles only modified binaries. The project explicitly avoids background network calls, limiting connectivity to a single weather API request from the status bar. This design choice reduces both network exposure and wake-time signaling, though it requires users to manually check for updates.

Permissions are granular and refusable, with each grant tied to a specific feature. Accessibility permissions enable window management, Input Monitoring supports the Super key remap and trackpad swipes, and Screen Recording allows live window previews. Without these, corresponding features either fail silently or fall back to basic functionality. The project acknowledges its current state as a 'works for me' implementation, with deliberate generalization for multi-display setups but no formal support guarantees.
